Genes affected

ADARB1 (HGNC:226): (adenosine deaminase RNA specific B1) This gene encodes the enzyme responsible for pre-mRNA editing of the glutamate receptor subunit B by site-specific deamination of adenosines. Studies in rat found that this enzyme acted on its own pre-mRNA molecules to convert an AA dinucleotide to an AI dinucleotide which resulted in a new splice site. Alternative splicing of this gene results in several transcript variants, some of which have been characterized by the presence or absence of an ALU cassette insert and a short or long C-terminal region.

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 0 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), ADARB1. . Trascript score misZ 3.725 (greater than threshold 3.09). GenCC has associacion of gene with neurodevelopmental disorder with hypotonia, microcephaly, and seizures.

BP4

Computational evidence support a benign effect (MetaRNN=0.13229132).

BS1

Variant frequency is greater than expected in population amr. gnomad4_exome allele frequency = 0.000072 (105/1458222) while in subpopulation AMR AF= 0.000273 (12/43988). AF 95% confidence interval is 0.000157. There are 0 homozygotes in gnomad4_exome. There are 50 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
